To all whom/ 711 Hm/y concern.-

Be it known that 1', EDGAR J. BLOOM, a citi- Zen of the United States, residing at Tiflin in the county of Seneca and State of Ohio, have invented a new and useful Flushing-Valve, of which thci following is a specification.

This invention relates to flushing-valves.

The objects of the invention are to improve, strengthen, and simplify the construction of such devices and to increase their efficiency and reliability in action.

With these and other objects in view, which will be apparent hereinafter, the invention resides in the novel combination and arrangement of parts, and in the details of construction particularly described with reference to the accompanying drawings, forming part of this specification, wherein- Figure 1 is a vertical longitudinal section, partly in elevation; and Fig. 2 1s a side ele-' vation.

The improved device comprises a casing 1 having an inlet 2, adapted to be connected with waterworks-supply, tank, or other suitable source of supply, and an outlet 3, adapted to be connected with suitable piping leading into the bowl to be flushed. Within the casing 1 is a double-ended piston 4, comprising the heads 5 and 6, connected by a spindle 7. Each of the piston-heads 5 and 6 is formed in its outer end with a cavity or socket, (denoted by 8 and 9.) Disks or cushions 10 and .11, of rubber or other suitable material, are placed one in each of the sockets 8 and 9 of the piston-heads.

The two ends of the casing 1 are closed by screw-plugs 12 and 13, each of which is formed with a tubular extension 14 and 15 and a bore or passage 16 and 17. It will be observed that when the piston 4 is at one end of the casing the tubular extension of one plug, 12 or 13, projects into the socket of the adjacent pistonhead and when said piston is at the opposite end of the casing the tubular extension of the other plug projects into the socket of the other piston-head. Moreover, it will be observed that when the piston is at one end or the other of the casing one or the other of its heads 5 6 always closes the inlet 2 and outlet 3, and, furthermore, it will be apparent that while said piston traversing the cylinder in either direction water is permitted to pass from the inlet 2 to the outlet 3 around the centrai spindle 7 of the piston.

lommunicating with the bore '16 of the plug 12 is a passage 18, which leads into the valvecasing 19 of a four-way valve 20, that controlled by means of a lever or handle 21. A passage 22 communicates with the valve-casing 19 and with the bore 17 of the plug 13. A similar passage 23 extends from the inlet 2 to the valve-casing 19 and a similar passage 2a from said valve easing to the outlet The construction of the four-way valve is such that when it is moved in one direction communication is opened between one of the end plugs and the inlet 2 and between the opposite end plug and the outlet Formed upon the valve 20 adjacent to its operating-handle is a segment 25, the movement of which is limited and adjusted by means of adjusting-screws 26 27. By turning the screws 26 27 to limit the throw of the valve the quantity of water 'iermitted to pass in a given time from the inlet to one of the end plugs and from the opposite end plug to the outlet may be regulated for a purpose to be set forth in the description of operation.

Constructed as described, the improved device operates in the following manner: Let it be supposed that the double-ended piston t is at the left end of the casing, with the tubular extension 15 of the plug 13 projecting into the socket 9 of the pistmi-head (3 against the rubber disk 11' and with the piston-head 5 closing the inlet 2 and outlet 3. The valve 20 then will be in such position as to permit communication between the end plug 1? and the outlet 3 and between the inlet 2 and the end plug 12. Now if the handle 21 of the valve 20 be moved to the position shown in dotted lines communicatimi will he opened between the inlet 2 and the end plug 13 and between the end plug 12 and the outlet 5). Water then will flow from the inlet 2 through passage 23, valve 20, passage 22, and bore 17 and will impinge against the head (3 of thepiston 1;, causing said piston to move steadily to the right. As soon as the piston-head 5 uncov ers the inlet 2 and outlet 3 a large volume of water rushes through the casing 1 around the spindle 7 from the inlet to the outlet to flush l All this while the piston 4 is mov- 1 ing steadily to the right under the impetus the bowl.

of the water passing from the inlet to the end plug 13. Itwill be understood that the water left in the opposite end of the casing by the previous operation of the device is steadily exhausting through the end plug 12, passage 18, valve 20, and passage 24 to the outlet 3. \Vhen the piston 4 reaches the end of its stroke, the inlet 2 andoutlet 3 are closed by the head 6, and the passage of water from the inlet 2 to the end plug 13 is stopped, because no more water can enter the casing. The piston remains in this position until the valve 20 is again actuated, when the operation just described repeats itself in the opposite direction.

It will be obvious that the quantity of water used for flushing the bowl and the length of time during which it shall be permitted to run can be regulated by means of the adjusting-screws 26 27. If the valve be permitted but partially to open, the water passes more slowly from the inlet to one of the end plugs.

Consequently the piston will move more slowly, and the flushing operation will be prolonged.

It will be apparent that other means than the lever 21 may be employed to actuate the valve 20, and the invention therefore is not to be limited to the use of a lever-handle.

At each end of its stroke the piston seats itself quietly against the end plug 'without The device is therefore renshock or jar. dered more strong and its period of usefulness is greatly prolonged. Furthermore, the cushions 10 11, seating against the tubular extensions 14 15 of plugs 12 or 13, act as valves, thus shutting off any water leaking past piston-heads 5 6. Furthermore, the device is simple, compact, neat, and inexpensive in construction and is adapted to be applied easily and quickly to different forms of sanitary apparatus.

In its novel combination and arrangement of parts, as well as its method of operation and details of construction, the device of this invention presents an improvement over prior devices used for a similar purpose.
